Hardware Requirements
All new IBM personal computers and clones are supplied with a standard 9-pin
male serial port, which uses the standard 9-pin extender cable.
If your computer has only one serial port connection being used by your mouse,
you will have to either add a second serial port for connecting to the ECM-100, or
unplug the mouse and connect the cable going to the ECM-100 and operate your
computer from the keyboard. This may require rebooting.
CAUTION:
Nearly all computers have a 25-pin male connector, which is a parallel
printer port. Do not connect the ECM-100, modem or any other serial
device to this port.
If your computer has a 25-pin female connector (most likely a serial port), then
you will need to use either a 9-pin (M) to 25-pin (M) adapter connector with a
standard 9-pin extender cable, or a 9-pin (M) extender cable instead. A M-M
(male-to-male) or F-F (female-to-female) gender adapter may be needed if the
available extender cable has the wrong port connection. Alternately, a USB to 9-
pin adapter can be used.
All of these parts are commercially available at computer and office supply
stores.
6.3.4 Printer Connections
Connecting to a Serial Printer
Nearly all serial printers have a 25-pin female connector, so you will
need a 9-pin (M) to 25-pin (M) cable, or 9 x 25 adapter to use with
the standard 9-pin extender cable, and a “Null Modem” adapter or
cable type. In some cases a gender adapter may be needed with a
standard IBM serial printer cable or if your only available cable has
the wrong style end. These components are commercially available
at computer and office supply stores. The green and red wires at
terminals #45 and #47 can be switched to provide the same cross-
cross effect as a “Null-Modem.”
